Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a dust extraction device for a wall grooving machine. Background Technology
[0002] A wall grooving machine is an electric tool used to cut grooves on the surface of walls. It is mainly used in construction scenarios such as water and electricity installation and pipe laying to chisel grooves or trenches. The high-speed rotating blade or cutting wheel cuts the wall to meet the actual construction requirements. The grooving machine generates a lot of dust during the cutting process, which pollutes the construction environment and poses a serious threat to the health of operators. Existing dust removal technologies mostly use fixed dust hoods in conjunction with negative pressure suction. However, because the bottom of the dust hood is in direct hard contact with the wall, it may cause wear and tear on the wall surface. In addition, the unevenness of the wall may leave gaps between the wall and the dust hood, affecting the dust removal effect. At the same time, the dust extracted is re-entrained inside the dust removal equipment, and long-term accumulation can easily damage the dust removal equipment.
[0003] To address the above problems, a dust extraction device for a wall grooving machine has been developed. Utility Model Content
[0004] To overcome the shortcomings of existing dust removal technologies, such as the direct hard contact between the bottom of the dust collection hood and the wall, which may cause wear on the wall surface, and the possibility of gaps between the wall and the dust collection hood due to different wall flatness, affecting the dust collection effect, and the secondary re-entrainment of the collected dust inside the dust collection equipment, which can easily damage the dust collection equipment in the long run, this utility model provides a dust extraction device for a wall grooving machine.
[0005] The technical solution of this utility model is as follows: A dust extraction device for a wall grooving machine includes a dust extraction hood, four mounting holes on the upper part of the dust extraction hood, a dust extraction pipe connected to the upper front side of the dust extraction hood, a movable seat on the left side of the dust extraction hood, a dust extraction box connected to the upper side of the movable seat, the dust extraction box being connected to the left side of the dust extraction pipe, a dust collection frame slidably connected to the movable seat, the dust collection frame being located at the lower part of the dust extraction box, and a sealing mechanism provided on the dust extraction hood.
[0006] More preferably, the sealing mechanism includes a damper, four dampers are connected to the dust cover, each damper has a spring inside, a sliding frame is connected between the four dampers, four guide members are connected to the sliding frame, the guide members are slidably connected to the dust cover, and a rubber strip is connected to the lower side of the sliding frame.
[0007] More preferably, it also includes a dust suppression mechanism, which includes a water tank. The water tank is connected to the upper side of the dust collection box, and a nozzle is connected to the upper side of the dust collection box. A water pipe connects the nozzle and the water tank.
[0008] More preferably, the dust collection box is provided with a handle on the front side.
[0009] More preferably, the lower front side of the dust collection box is rotatably connected to a locking element that locks the dust collection frame.
[0010] More preferably, the upper part of the water tank is threaded with an anti-slip cap.
[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model uses a sealing mechanism where four symmetrically distributed dampers provide adaptive pressure through internal springs, driving the sliding frame to move vertically along the guide. The rubber strip causes the grooving machine to continuously deform when it comes into contact with walls of different flatness, always maintaining a flexible contact distance with the wall, thus forming a dynamic seal inside the dust collection hood, effectively preventing dust from overflowing, improving the dust collection effect, and avoiding excessive friction damage to the wall.
[0013] 2. This utility model uses a dust-reducing mechanism to fully mix the water mist atomized by the nozzle with the dust. Through wetting and coagulation, the dust becomes heavier and settles, reducing the concentration of suspended dust and facilitating dust collection. Attached Figure Description

Detailed Implementation
[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Example 1
[0021] A dust extraction device for a wall grooving machine, such as Figure 1 and Figure 2 As shown, it includes a dust collection hood 1, with four mounting holes 2 on the upper part of the dust collection hood 1. A dust extraction pipe 3 is connected to the upper front side of the dust collection hood 1. A movable base 4 is provided on the left side of the dust collection hood 1. A dust collection box 5 is connected to the upper side of the movable base 4. The dust collection box 5 is connected to the left side of the dust extraction pipe 3. A handle is provided on the front side of the dust collection box 5. A dust collection frame 6 is slidably connected to the movable base 4. The dust collection frame 6 is located at the lower part of the dust collection box 5. A locking element that locks the dust collection frame 6 is rotatably connected to the lower front side of the dust collection box 5. A sealing mechanism 7 is provided on the dust collection hood 1.
[0022] like Figure 1 and Figure 3 As shown, the sealing mechanism 7 includes a damper 72. Four dampers 72 are connected to the dust cover 1. Each damper 72 has a spring 73 connected inside. A sliding frame 71 is connected between the four dampers 72. Four guides 74 are connected to the sliding frame 71. The guides 74 are slidably connected to the dust cover 1. A rubber strip 75 is connected to the lower side of the sliding frame 71.
[0023] It should be noted that a wall grooving machine is an electric tool used to cut grooves on wall surfaces. It is mainly used in construction scenarios such as water and electricity installation and pipe laying to chisel grooves or trenches. High-speed rotating blades or cutting wheels cut the wall to meet actual construction requirements. With the assistance of a dust extraction device, dust-free or low-dust operation can be achieved. In use, first, the dust extraction device is fixed to the grooving machine through mounting hole 2. The operator controls the grooving machine to perform the grooving operation. When the grooving machine starts, the negative pressure fan built into the dust extraction box 5 operates synchronously, creating a continuous negative pressure inside the dust extraction hood 1 through the dust extraction pipe 3. The dust generated during cutting is sucked into the dust extraction pipe 3 under the negative pressure and enters the dust extraction box 5. The dust settles in the dust collection frame 6. When the dust collection volume reaches the threshold, the operator can rotate the locking device to lock the dust collection frame 6 in place. 5. Release the locked state and pull out the dust collection frame 6 for cleaning. Since the bottom of the dust hood 1 is in direct hard contact with the wall, it may cause wear on the wall surface. In addition, different flatness of the wall may cause gaps between the wall and the dust hood 1, affecting the dust extraction effect. The above problems can be avoided by the sealing mechanism 7. The four dampers 72 symmetrically distributed on the dust hood 1 provide adaptive pressure through the internal spring 73, which drives the sliding frame 71 to move vertically along the guide 74. When the grooving machine contacts the wall surface with different flatness, the rubber strip 75 deforms under continuous pressure, always maintaining a flexible contact distance with the wall surface, so that a dynamic seal is formed inside the dust hood 1, which effectively prevents dust from overflowing, improves the dust extraction effect, and avoids excessive friction damage to the wall surface. When it is necessary to push the moving seat 4 to move, the handle can be used to push the equipment to achieve smooth movement of the equipment.
[0024] Example 2
[0025] Based on Example 1, such as Figure 1 and Figure 4 As shown, it also includes a dust suppression mechanism 8, which includes a water tank 81. The upper side of the dust collection box 5 is connected to the water tank 81, and the upper part of the water tank 81 is threaded with an anti-slip cap. The upper side of the dust collection box 5 is connected to a nozzle 83, and a water pipe 82 is connected between the nozzle 83 and the water tank 81.
[0026] It should be noted that when the dust extraction box 5 draws dust into the dust collection frame 6, small dust particles will be suspended in the upper part of the dust extraction box 5 and the dust collection frame 6. The water in the water tank 81 forms a water mist through the water pipe 82 and the nozzle 83. The water mist mixes and comes into contact with the dust, causing the dust to become heavier and settle, reducing the dust suspension concentration and facilitating dust collection. At the same time, the anti-slip knob can be rotated to add water to the water tank 81, which is conducive to the continuous dust suppression operation.
[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
